A silky Sri Lankan-style coconut and jaggery custard pudding, brightened with toasted sesame and a touch of lime.
Watalappan, a rich steamed custard made from coconut milk, jaggery, eggs and warm spices like cardamom and nutmeg, is one of Sri Lanka's most treasured desserts, closely tied to the island's Malay community and traditionally served at celebrations. This version keeps the essential watalappan technique — coconut milk and jaggery custard, steamed gently until set — while adding a scatter of toasted sesame seeds and a touch of lime zest, both modern, non-traditional additions layered onto the authentic base. Jaggery, unrefined palm or cane sugar with a deep caramel-molasses flavor, is what gives watalappan its distinctive dark color and rich sweetness — white sugar simply doesn't replicate the same depth, so it's worth seeking out. The custard, whisked from eggs, coconut milk, melted jaggery and warm spices, is steamed gently in a water bath rather than baked directly, which keeps the texture silky rather than curdled or rubbery. A finish of toasted sesame seeds and a little lime zest, stirred in or scattered on top just before serving, adds a nutty crunch and citrus brightness that cuts through the pudding's deep sweetness.
Serves 6
Combine jaggery and water in a small saucepan over medium heat. Stir until fully melted and smooth, then strain to remove any impurities. Let cool slightly.
Whisk the eggs in a large bowl, then gradually whisk in the melted jaggery syrup, coconut milk, cardamom, nutmeg and salt until smooth.
Pour the custard through a fine sieve into a greased heatproof dish to remove any egg strands, then cover the dish tightly with foil.
Place the dish in a larger baking pan and add hot water to reach halfway up the sides. Steam in a 160C (320F) oven for 40-45 minutes until just set with a slight jiggle in the center.
Remove from the water bath and let cool to room temperature, then refrigerate at least 2 hours until fully set.
Scatter with toasted sesame seeds, lime zest and toasted cashews just before serving.
Strain the jaggery syrup before mixing it into the custard — jaggery often contains small bits of fiber or sediment that are best removed.
Steam gently in a water bath rather than baking the custard directly, or it will curdle and turn grainy instead of silky.
Check for doneness with a gentle jiggle test — the center should wobble slightly but not look liquid; it will continue to set as it chills.
Classic version: skip the sesame and lime zest entirely for a traditional, unadorned watalappan.
Extra richness: use full-fat, first-press coconut milk for the creamiest, most traditional texture.
No jaggery available: substitute dark brown sugar mixed with a tablespoon of molasses, though the flavor will be slightly different from true jaggery.
Refrigerate covered up to 4 days. Serve chilled directly from the fridge; the texture is best within the first 2-3 days.
Watalappan is a celebrated Sri Lankan dessert with roots in the island's Malay community, traditionally served at festive occasions and family gatherings. Made from coconut milk, jaggery and warm spices like cardamom, it reflects Sri Lanka's broader culinary blending of South and Southeast Asian influences, and remains one of the country's most iconic sweets today.
Jaggery is unrefined palm or cane sugar with a deep, caramel-like flavor that's essential to watalappan's distinctive taste and color. Dark brown sugar with a little molasses is the closest substitute, though it won't fully replicate jaggery's complexity.
This usually happens if the custard was baked at too high a temperature or without a water bath, causing the eggs to curdle. Keep the oven temperature moderate and always steam the custard in a water bath for a silky texture.
No — traditional watalappan is typically garnished with cashews alone. The sesame and lime zest here are modern additions for extra texture and brightness, easily left out for a classic version.
